Hilary Duff: 'Being a parent is no joke'

Hilary Duff has said that she is finding that parenthood can be tough, adding that raising a child is "no joke".

The 24-year-old actress and singer, who gave birth to baby boy Luca Cruz on March 20, said that she feels very tired after getting up for nighttime feeds.

Duff wrote on her Twitter page: "4am... sleepy eyed. Feeding baby... whew this job is no joke!"

Earlier this week, Duff revealed on the microblogging website that her older sister Haylie had gone over to her house to make Hilary and husband Mike Comrie a kale salad and truffle devilled eggs, adding: "I think it's more about her getting time with Luca, but I take it."

When she first announced Luca's birth, Hilary said: "We are overjoyed and feel like the luckiest parents in the world. He is surrounded by so much love!! Mom and baby are both doing extremely well."

She later added: "Wow, I can't believe I have a baby! Thank you for all the messages and well wishes. I love you all so much."

During her pregnancy, Hilary admitted that she was "afraid" of motherhood, adding: "It's not something you want to mess up and it's not something to take lightly. Obviously I want to be really good at it. We'll figure it out just like everyone else does."
